Abstract
BACKGROUND: Mental health issues among PhD students are rising, a trend believed to be driven by academic and social challenges. METHOD: A total of 1265 doctorate students from a large university in Barcelona, Spain (739 women; 414 men; 112 marked other options), with a mean age of 32.36 years (SD = 8.20, range: 23-67), were evaluated by means of standardized instruments. RESULTS: Totals of 40.6% and 46.5% of the sample exceeded the cut-off point for anxiety and depression symptoms, and 57.7% for life satisfaction. The proportion of females exceeding the cut-off point was significantly higher than that of males for both anxiety (women: 43.8%, men: 34.5%) and depression (women: 49.3%, men: 39.8%), but not for life satisfaction (women: 57.6%, men: 58.4%). Arts and Humanities PhD students' disciplines reported higher anxiety and depression scores than those in Social Sciences, Experimental Sciences and Mathematics, and Health Sciences, respectively, while Social Sciences students showed higher life satisfaction and mentoring support than the other groups. Depression scores were significant predictors of life satisfaction across all doctoral programs. CONCLUSIONS: These findings highlight the importance of mentoring in supporting doctoral students' mental health and life satisfaction and can also inform policies in educational institutions, given that PhD students experiencing psychopathological disorders are at a higher risk of academic failure and dropout.
